Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a two-part polyurethane resin composition which is excellent in foam suppression and in slump resistance in the hardening process even under high-temperature and high-humidity circumstances and which presents a good external appearance. SOLUTION: The two-part polyurethane resin composition contains a calcium carbonate whose surface has a BET specific surface area of not less than 8 m2/g. The surface of the calcium carbonate is treated with an organic mixture comprising at least one organic matter (A) selected from the group consisting of alkylated aromatic sulfonic acids and their metallic salts and at least one organic matter (B)selected from the group consisting of aliphatic acids and their metallic salts. In the surface-treatment mixture, the organic matters (A) and (B) are not metallic salts at the same time, the weight ratio (A)/(B) is 0.05-1, and the BET specific surface area and the treated surface area satisfy the inequality: 1
